Systems and methods for miniaturized drawbar extension springs
| Abstract: Extension springs that can be manufactured to a small size with a precise free length are described herein. An extension spring comprises a first drawbar member and a second drawbar member that extend along a same direction. The extension spring further comprises a compression spring coil that surrounds respective portions of the draw bar members. At either end of the spring coil are positioned end caps that surround the drawbar members. The end caps provide flat surfaces on which the ends of the spring coil rest in a resting position of the extension spring. The end caps are held against bent ends of arms of the drawbar members by tension of the spring coil. When the drawbar members are drawn apart from one another, the end caps compress the spring coil. Compression of the spring coil causes forces that resist the motion of the drawbar members apart from one another. |
